First Quarter 2022 Results²

Tim Boswell, President and Chief Financial Officer of WillScot Mobile Mini Holdings, commented “Our outstanding results in the first quarter reflect a continuation of the trends we saw exiting 2021. Our commercial momentum in particular is exceeding our own high expectations and we continue to invest accordingly. Leasing revenue increased $78 million or 25% year-over-year, driven by strength across all leasing KPIs and in all segments. Gross Profit Margin expanded by 227 basis points, led by our improved delivery and installation margins, which is indicative of our ability to pass through inflationary pressures. And we continue to ramp up resources, particularly in the areas of sales and direct labor, to support our growing demand backlog with total headcount up 12% year-over-year and up 3% sequentially from the fourth quarter. These factors resulted in Adjusted EBITDA of $192 million, representing a 17% increase year-over-year.”

Boswell continued, “Cash flow from operations continued to accelerate up 19% year-over-year to $146 million, and we reinvested aggressively based on the results we saw from our growth initiatives. We invested $91 million in Net Capex, which was demand-driven and focused on organic portable storage unit acquisition, modular refurbishments, and VAPS, leaving $55 million of Free Cash Flow during the quarter. Finally, we closed one acquisition during the quarter and another two transactions in April. And we returned $77 million to shareholders by repurchasing 2.1 million shares during the quarter. All of this is consistent with our long-term capital allocation and value creation frameworks.”

“Given the strong performance of the business year-to-date and our outlook for the remainder of the year, we are raising our guidance to $2.1B to $2.2B of revenue and $860 million to $900 million of Adjusted EBITDA. At the midpoints of these ranges, Adjusted EBITDA margin would expand approximately 200 basis points year-over-year and put us on an exciting run-rate heading into 2023. Regardless of the economic backdrop, we are focused on the levers within our control to grow our predictable reoccurring revenue streams, compound cash generation, and drive even higher returns on invested capital, and we expect outstanding results in the remainder of 2022.”

NA Modular

• Revenue of $299.7 million increased by 12.6% year-over-year.
  • Average modular space monthly rental rate increased $147 year-over-year, or 19.9% to $884.
  • Average modular space units on rent increased 212 units year-over-year, or 0.3% to 85,007, consistent with our expectations for UOR inflection in the first half of 2022. Sequentially from December 31, 2021, modular space units on rent increased by approximately 1,800 units, or 2.1%. Excluding units acquired from acquisitions during the quarter, sequential modular space units on rent from December 31, 2021 increased by approximately 1,400 units, or 1.7%.
  • Value-Added Products and Services (VAPS) average monthly rate increased $57 year-over-year, or 29% to $251. For delivered units over the last twelve months, VAPS average monthly rate increased $70 year-over-year, or 21%, to $407.
• Adjusted EBITDA of $103.9 million increased by 6.7% year-over-year. The transfer of the NA Modular portable storage fleet to the NA Storage segment in Q3 2021 represented a decline of about $5 million of revenue and EBITDA in Q1 2022, which has not been adjusted historically.

NA Storage

• Revenue of $151.5 million increased by 40.5% year-over-year.
  • Average portable storage monthly rental rate increased $18 year-over-year, or 12.2% to $166.
  • Average portable storage units on rent increased by 46,516 units year-over-year, or 44.0% to 152,326. Of this increase, approximately 19,000 units on rent were driven by organic volume growth. The remainder of the increase was driven by the acquisition of approximately 15,500 average units on rent during Q3 and Q4 2021 and the transfer of approximately 12,000 units from NA Modular (legacy WillScot) into the NA Storage segment that was completed in Q3 2021.
  • Average modular space monthly rental rate increased $59 year-over-year, or 11.0%, to $594, and modular space average units on rent increased 2,120 year-over-year, or 12.9%, to 18,559.
• Adjusted EBITDA of $63.8 million increased by 37.8% year-over-year. The transfer of the NA Modular portable storage fleet to the NA Storage segment in Q3 2021 represented an increase of about $5 million of revenue and EBITDA in Q1 2022, which has not been adjusted historically.

UK Storage

• Revenue of $27.4 million increased 1.5% year-over-year, driven by continued strong price and volume trends partially offset by the impact of unfavorable foreign exchange rates, and Adjusted EBITDA of $12.5 million increased by 12.6%.

Tank and Pump

• Revenue of $30.3 million increased 24.7% year-over-year, driven by tightening OEC utilization, and Adjusted EBITDA of $11.5 million increased by 30.7%.

Capitalization and Liquidity Update²

As of March 31, 2022

• Repurchased 2.1 million shares of Common Stock and stock equivalents for $77 million in the first quarter 2022, contributing to a 3.8% reduction in our economic share count over the last twelve months. As of March 31, 2022, $879 million of the $1.0 billion share repurchase authorization remained.
• $647 million of excess availability under the asset-based revolving credit facility, a flexible covenant structure, and accelerating free cash flow provide ample liquidity to fund multiple capital allocation priorities.
• Weighted average interest rate is approximately 3.9% and annual cash interest expense based on the current debt structure is approximately $113 million.
• No debt maturities prior to 2025.
• Maintained leverage at 3.6x last-twelve-months Adjusted EBITDA of $769 million and maintaining our target range of 3.0x to 3.5x.

2022 Outlook ^{2, 3, 4}

This guidance is subject to risks and uncertainties, including those described in “Forward-Looking Statements” below.

		2021 Results		Prior 2022 Outlook		Current 2022 Outlook
Revenue		$1,895 million		$1,925 million – $2,025 million		$2,100 million – $2,200 million
Adjusted EBITDA1,2		$740 million		$810 million – $850 million		$860 million – $900 million
Net CAPEX2,3		$237 million		$225 million – $275 million		$275 million – $325 million
1 – Assumes common shares outstanding plus treasury stock method from warrants outstanding as of 3/31/2021 versus 3/31/2022 and the closing stock price of $39.13 on 3/31/2022. 2 – Adjusted EBITDA, Adjusted EBITDA Margin, Free Cash Flow, Free Cash Flow Margin, Net Income Excluding Gain/Loss from Warrants, and Return on Invested Capital are non-GAAP financial measures. Further information and reconciliations for these non-GAAP measures to the most directly comparable financial measure under generally accepted accounting principles in the US (“GAAP”) is included at the end of this press release. 3 – Information reconciling forward-looking Adjusted EBITDA and Net CAPEX to GAAP financial measures is unavailable to the Company without unreasonable effort and therefore no reconciliation to the most comparable GAAP measures is provided. 4 – Net CAPEX is a non-GAAP financial measure. Please see the non-GAAP reconciliation tables included at the end of this press release.

Non-GAAP Financial Measures

This press release includes non-GAAP financial measures, including Adjusted EBITDA, Adjusted EBITDA Margin, Free Cash Flow, Free Cash Flow Margin, Return on Invested Capital, Adjusted Gross Profit, Adjusted Gross Profit Percentage, Net Income Excluding Gain/Loss from Warrants, and Net CAPEX. Adjusted EBITDA is defined as net income (loss) plus net interest (income) expense, income tax expense (benefit), depreciation and amortization adjusted to exclude certain non-cash items and the effect of what we consider transactions or events not related to our core business operations, including net currency gains and losses, goodwill and other impairment charges, restructuring costs, costs to integrate acquired companies, costs incurred related to transactions, non-cash charges for stock compensation plans, gains and losses resulting from changes in fair value and extinguishment of common stock warrant liabilities, and other discrete expenses. Adjusted EBITDA Margin is defined as Adjusted EBITDA divided by revenue. Free Cash Flow is defined as net cash provided by operating activities, less purchases of, and proceeds from, rental equipment and property, plant and equipment, which are all included in cash flows from investing activities. Free Cash Flow Margin is defined as Free Cash Flow divided by revenue. Return on Invested Capital is defined as adjusted earnings before interest and amortization divided by net assets. Adjusted earnings before interest and amortization is the sum of income (loss) before income tax expense, net interest (income) expense, amortization adjusted for non-cash items considered non-core to business operations including net currency (gains) losses, goodwill and other impairment charges, restructuring costs, costs to integrate acquired companies, non-cash charges for stock compensation plans, gains and losses resulting from changes in fair value and extinguishment of common stock warrant liabilities, and other discrete expenses, reduced by our estimated statutory tax rate. Given we are not a significant US taxpayer due to our current tax attributes, we include estimated taxes at our current statutory tax rate of approximately 25%. Net assets is total assets less goodwill and intangible assets, net and all non-interest bearing liabilities and is calculated as a five quarter average. Adjusted Gross Profit is defined as gross profit plus depreciation of rental equipment. Adjusted Gross Profit Percentage is defined as Adjusted Gross Profit divided by revenue. Net Income Excluding Gain/Loss from Warrants is defined as net income plus or minus the change in the fair value of the common stock warrant liability. Net CAPEX is defined as purchases of rental equipment and refurbishments and purchases of property, plant and equipment (collectively, “Total Capital Expenditures”), less proceeds from the sale of rental equipment and proceeds from the sale of property, plant and equipment (collectively, “Total Proceeds”), which are all included in cash flows from investing activities. The Company believes that Adjusted EBITDA and Adjusted EBITDA margin are useful to investors because they (i) allow investors to compare performance over various reporting periods on a consistent basis by removing from operating results the impact of items that do not reflect core operating performance; (ii) are used by our board of directors and management to assess our performance; (iii) may, subject to the limitations described below, enable investors to compare the performance of the Company to its competitors; (iv) provide additional tools for investors to use in evaluating ongoing operating results and trends; and (v) align with definitions in our credit agreement. The Company believes that Free Cash Flow and Free Cash Flow Margin are useful to investors because they allow investors to compare cash generation performance over various reporting periods and against peers. The Company believes that Return on Invested Capital provides information about the long-term health and profitability of the business relative to the Company’s cost of capital. The Company believes that Adjusted Gross Profit and Adjusted Gross Profit Percentage are useful to investors because they allow investors to assess gross profit excluding non-cash expenses, which provides useful information regarding our results of operations and assists in analyzing the underlying performance of our business. The Company believes that Net Income Excluding Gain/Loss from Warrants is useful to investors because it removes the impact of stock market volatility from our operational results. The Company believes that the presentation of Net CAPEX provides useful information to investors regarding the net capital invested into our rental fleet and plant, property and equipment each year to assist in analyzing the performance of our business. Adjusted EBITDA is not a measure of financial performance or liquidity under GAAP and, accordingly, should not be considered as an alternative to net income or cash flow from operating activities as an indicator of operating performance or liquidity. These non-GAAP measures should not be considered in isolation from, or as an alternative to, financial measures determined in accordance with GAAP. Other companies may calculate Adjusted EBITDA and other non-GAAP financial measures differently, and therefore the Company’s non-GAAP financial measures may not be directly comparable to similarly-titled measures of other companies. For reconciliation of the non-GAAP measures used in this press release (except as explained below), see “Reconciliation of Non-GAAP Financial Measures” included in this press release.

Information reconciling forward-looking Adjusted EBITDA to GAAP financial measures is unavailable to the Company without unreasonable effort. We cannot provide reconciliations of forward-looking Adjusted EBITDA to GAAP financial measures because certain items required for such reconciliations are outside of our control and/or cannot be reasonably predicted, such as the provision for income taxes. Preparation of such reconciliations would require a forward-looking balance sheet, statement of income and statement of cash flow, prepared in accordance with GAAP, and such forward-looking financial statements are unavailable to the Company without unreasonable effort. Although we provide a range of Adjusted EBITDA that we believe will be achieved, we cannot accurately predict all the components of the Adjusted EBITDA calculation. The Company provides Adjusted EBITDA guidance because we believe that Adjusted EBITDA, when viewed with our results under GAAP, provides useful information for the reasons noted above.

Reconciliation of Non-GAAP Financial Measures

In addition to using GAAP financial measurements, we use certain non-GAAP financial information that we believe is important for purposes of comparison to prior periods and development of future projections and earnings growth prospects. This information is also used by management to measure the profitability of our ongoing operations and analyze our business performance and trends.

We evaluate business segment performance on Adjusted EBITDA, a non-GAAP measure that excludes certain items as described in the reconciliation of our consolidated net income (loss) to Adjusted EBITDA reconciliation below. We believe that evaluating segment performance excluding such items is meaningful because it provides insight with respect to intrinsic operating results of the Company.

We also regularly evaluate gross profit by segment to assist in the assessment of the operational performance of each operating segment. We consider Adjusted EBITDA to be the more important metric because it more fully captures the business performance of the segments, inclusive of indirect costs.

We also evaluate Free Cash Flow, a non-GAAP measure that provides useful information concerning cash flow available to fund our capital allocation alternatives.

Adjusted EBITDA

We define EBITDA as net income (loss) plus interest (income) expense, income tax expense (benefit), depreciation and amortization. Our adjusted EBITDA (“Adjusted EBITDA”) reflects the following further adjustments to EBITDA to exclude certain non-cash items and the effect of what we consider transactions or events not related to our core business operations:

• Currency (gains) losses, net: on monetary assets and liabilities denominated in foreign currencies other than the subsidiaries’ functional currency. Substantially all such currency gains (losses) are unrealized and attributable to financings due to and from affiliated companies.
• Goodwill and other impairment charges related to non-cash costs associated with impairment charges to goodwill, other intangibles, rental fleet and property, plant and equipment.
• Restructuring costs, lease impairment expense, and other related charges associated with restructuring plans designed to streamline operations and reduce costs including employee and lease termination costs.
• Transaction costs including legal and professional fees and other transaction specific related costs.
• Costs to integrate acquired companies, including outside professional fees, non-capitalized costs associated with system integrations, non-lease branch and fleet relocation expenses, employee training costs, and other costs required to realize cost or revenue synergies.
• Non-cash charges for stock compensation plans.
• Gains and losses resulting from changes in fair value and extinguishment of common stock warrant liabilities.
• Other expense includes consulting expenses related to certain one-time projects, financing costs not classified as interest expense, and gains and losses on disposals of property, plant, and equipment.

Adjusted EBITDA has limitations as an analytical tool, and you should not consider the measure in isolation or as a substitute for net income (loss), cash flow from operations or other methods of analyzing the Company’s results as reported under US GAAP. Some of these limitations are:

• Adjusted EBITDA does not reflect changes in, or cash requirements for our working capital needs;
• Adjusted EBITDA does not reflect our interest expense, or the cash requirements necessary to service interest or principal payments, on our indebtedness;
• Adjusted EBITDA does not reflect our tax expense or the cash requirements to pay our taxes;
• Adjusted EBITDA does not reflect historical cash expenditures or future requirements for capital expenditures or contractual commitments;
• Adjusted EBITDA does not reflect the impact on earnings or changes resulting from matters that we consider not to be indicative of our future operations;
• although depreciation and amortization are non-cash charges, the assets being depreciated and amortized will often have to be replaced in the future and Adjusted EBITDA does not reflect any cash requirements for such replacements; and
• other companies in our industry may calculate Adjusted EBITDA differently, limiting its usefulness as a comparative measure.

Because of these limitations, Adjusted EBITDA should not be considered as discretionary cash available to reinvest in the growth of our business or as measures of cash that will be available to meet our obligations.

Return on Invested Capital

Return on Invested Capital is defined as adjusted earnings before interest and amortization divided by net assets. Adjusted earnings before interest and amortization is the sum of income (loss) before income tax expense, net interest (income) expense, amortization adjusted for non-cash items considered non-core to business operations including net currency (gains) losses, goodwill and other impairment charges, restructuring costs, costs to integrate acquired companies, non-cash charges for stock compensation plans, gains and losses resulting from changes in fair value and extinguishment of common stock warrant liabilities, and other discrete expenses, reduced by estimated taxes. Given we are not a significant US taxpayer due to our current tax attributes, we include estimated taxes at our current statutory tax rate of approximately 25%. Net assets is total assets less goodwill, and intangible assets, net and all non-interest bearing liabilities. Denominator is calculated as a five quarter average for annual metrics and two quarter average for quarterly metrics. The Company believes that Return on Invested Capital provides information about the long-term health and profitability of the business relative to the Company’s cost of capital.
